I have Facebook suggested a few albums today (2 hours ago). Some of them are from 2+ years ago, others are recent ones. The suggestion is quite accurate (89%, 8 out of 9 albums). With the incorrect album, Facebook suggested another city with the same name but from another country!
So Facebook probably just combine as much data as possible and when the matching rate is larger than some threshold, it will temporary tag the album and confirm with users. Data may include:
1. Album info (yeah, most of my album includes the place in it's name or description)
2. Comments group. 3 of my albums have a large number of comments, they are all from my highschool friends (I grouped them all in the same group) so it's quite accurate I guess. Also, if Facebook use the information in their smart lists, that makes sense too.
3. EXIF data. Some people says Facebook can read the data and cross-check the date with its database of check-in. This doesn't happen to me but I think it's possible. And of course, if the EXIF has geo-tagged, that info can be picked up.
Thought?
- Pedrom 15y agoGuessing from that data might still be using machine learning (e.g Collaborative filtering). I guess you meant it is not computer vision related. At this point I don't think it matters too much, they are using a combination of techniques (including the famous social graph) and that is giving good results.
- emw 15y agoI second the idea that this doesn't sound like machine learning. I wouldn't be surprised if there were no machine learning or data mining algorithms involved in Facebook mapping EXIF-embedded geographic coordinates in digital photographs and suggesting locations for an album based on points-of-interest near those coordinates. Maybe some neat work with GIS enabled this, but I don't see anything that strongly indicates machine learning.
